Thank you Catherine
and George for your GREAT question!!
How much blood you could
loose before real trouble?
Loss of 10-15%
of total blood volume can be endured without needing any clinical intervention.
A blood donation typically takes 8-10% of the donor’s blood volume.
Class I Hemorrhage -
15% blood loss - typically no change in vital signs.
II Hemorrhage - 15-30% blood loss - rapid heart beat, start to look pale and
feel cool since body is trying to compensate by constricting the vessels - Saline solution may be given.
Class III Hemorrhage - 30-40% blood loss
- blood pressure drops, heart rate increases, mental status worsens. Blood transfusion is necessary.
Class IV Hemorrhage - >40% blood loss - This
is the limit - aggressive resuscitation is required to prevent death.
The best place for your blood...
right where it is!
